Paul McCartney shed some light on his shaky performance at last summer's Olympic Opening Ceremony in London. McCartney spoke to The Daily Mail and revealed that the bizarre double vocal at the beginning of the song was due to McCartney going "rogue' and deciding not to lip-sync at the very last minute. McCartney admitted, "I f***up. I was supposed to wait for a cue. But I forgot. Why? Well there's this bloody great bell that we didn't know about. It was deafening.'

McCartney explained, "We were live, everyone was there, the world was ready and this bloody great bell goes off. And I forget I've gotta wait for it, so I go 'Hey Jude . . .' and someone presses the playback. So there's me on the backing track, and actual me; two of us singing. . . The drummer wouldn't look at me because he was in hysterics and I was thinking, 'What have I done?' There was no stopping, it was the Olympics."

McCartney admits that playing Beatles songs these days is a great way to revisit his time with John Lennon and George Harrison: "Y'know, the live experience is a mad one, because the same time that you're singing and remembering words and remembering chords -- you're off on one! And you're thinking 'Oh, Abbey Road, and I remember John coming up with. . . and what about when George said that?' And you go, 'Come back! Come back! Earth to Paul -- you're onstage! Don't go too far!' (Laughs) Y'know? But it is, it's great, you do look at the songs as if it's someone else."

Paul McCartney will next perform on Wednesday (December 12th) at 12-12-12: A Concert For Sandy Relief at Madison Square Garden.
